HYDRANT.

SPECIFICATION forming part of Letters Patent No. 451,518, dated May 5, 1891. Application filed January 26, 1891. Serial No. 379,085. (No model.)

To all whom it may concern:

Be it known that I, WHITMAN C. RATHBUN, a citizen of the United States, residing at Sioux City, in the county of IVoodbui-y and State of Iowa, have invented certain new and useful Improvements in Hydrants; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, lwhich form a part of this specification.

My invention has relation to waterhydrants, and the object is to provide improved means for withdrawing'the valve or valvechamber, when necessary for filing the seat or for cleaning the hydrant, without having to unearth the lower parts of the hydrant, and without loss of time or labor.

My invention therefore consists in the novel construction of the parts and their combination, as will be hereinafter described, and particularly pointed yout in the claim.

I have fully and clearly illustrated my invention in the accompanying d1awings,wheie in v Figure l is avertical section of hydrant, showing the parts which I claim to be of my own invention as used in connection with other well-known parts. Fig. 2 is a view showing circular chamber. Fig. 3 is a view showing block. Fig. 1l is a View showing valve-chamber.

Referring now to these illustrations, wherein like parts are designated by the same letters of reference, U designates a handle of ordinary construction, which operates the screw-R in the box T, and raises or lowers the core IV in the valve for the purpose of turning on or shutting off the water.

V V designate a small block adapted to screw onto the upper part of the chamber E E, through which runs theV screw R.

M designates the nozzle of the hydrant.

E E designate an upper chamber, A A a lower circular chamber, the upper chamber being constructed to iit down over the lower chamber far enough to allow it to be fastened to it by the set-screws m m', which fit into the circular groove n n', formed on the upper surface of chamber A A for that purpose. These chambers protect the valve and working parts from mud, dirt, and debris.

B designatcsa supporting-block of circular construction made to iit into and form the bottom support of the chamber A A. This block is provided with a hollow core on its upper surface threaded to receive the exten- 6o sion g of the valve-chamber I L, and a hollow core on one of its adjacent sides threaded to receive the supply-pipe X. Openings, as at n, are provided in the outer surface of the block B to receive the set-screws b b to hold it in place in the chamber A in a irm and solid manner. The valve-chamber I L is a brass chamber inclosing the core IV, and is provided with waste-holes c c and c e and the threaded extension g. Pipe II is con- 7o nected to the valve-chamber by a left-handed thread, which fits into a recess in the upper section I, made to receive it. The object of this is that the valve-chamber inclosing the valve may be unscrewed from the block B, which is connected by a right-handed thread, this making it impossible to unscrew anywhere but at block B, thus allowing the valvechamber to be unscrewed at g and to be withdrawn,with the inclosed valve,from above 8o for purposes of repairing without any digging or loss of time or labor.

fr r designate a washer which fit-s around g', directly under section L of the valve-chamber, and seals the valve in amost perfect manner. 8 5

d d designate cup-washers used to regulate the waste. The valve is inclosed within the valve-chamber, and the operation is as follows: By turning handle U the core IV is raised or lowered to turn the water on or off, 9o as desired. IVhen the valve is open, the water passes through the hole m and on up through pipe l? and out of nozzle M. I/Vhen the valve is closed, the water in pipe P wastes back out of hole m and through waste-holes c c and e e and out through waste-holes a a', thus keeping the water from freezing. The block B may be connected to the chamber A with set-screws, as shown, or may be threaded and screwed into the chamber A, which may loo be threaded to receive it.

I'Iaving thus fully and clearly described my invention, what I claim, and desire to secure the extension by Letters Patent, is

In a Water-hydrant, the combination of the block B, provided with threaded recesses to receive supply-pipe X and extension g of valve-chamber I L, suitable recesses to reccive set-screws b b', and adapted to be seg to connect with block I3, which is provided with a right-handed thread, and the valve provided with cup-Washers and 15 core, constructed as described, forthe purpose specified.

In testimony whereof I affix 1n y signnturein presence of two Witnesses.

cured to the chamber A and to form a supporting-base thereof, the valve-chamber I L, 'IIITMAN C. RATIIBUN. provided with Waste-openings c c and e e Witnesses:

and adapted to receive the pipe II, provided with a leftdmnded thread and by means of l GUY C. RICH, CHARLES F. IECAUT.
